Roller derby The Twin Cities is home to Minnesota Roller Derby (Saint Paul), North Star Roller Derby (Minneapolis) and Twin Cities Roller Derby (Minneapolis), as well as two junior derby leagues, Minnesota Junior Roller Derby (MNJRD) and Minnesota Frostbite. Minnesota Roller Derby was founded in 2004 as the Minnesota RollerGirls, and were the fourth flat-track league to host a bout. Their venue for the first season was a roller rink in a northern Minneapolis suburb. After selling out all four bouts in their first season, they were approached by the City of Saint Paul, which connected them with the Roy Wilkins Auditorium, part of the RiverCentre Complex, making them the first modern roller derby league to play in a professional sports venue, and their first sellout set the modern roller derby attendance record of 4,900 (which was beaten the next month by the Rat City Rollergirls of Seattle, who had recently begun playing in the 15,000-seat KeyArena). The Minnesota RollerGirls are founding members of the Women's Flat-Track Derby Association (WFTDA), the main governing body for flat track roller derby, and have advanced to the WFTDA Championships in 2006, 2010, 2011, and 2012. Minnesota Roller Derby's training organization includes the adult training team Minnesota Windchill (formerly Debu-Taunts) and junior training team Minnesota Frostbite. North Star Roller Derby was founded in 2006 as North Star Roller Girls, and played in a roller rink for two seasons before moving to the Minneapolis Convention Center. They joined the WFTDA in 2009, and competed in the North Central Regional Tournament in 2009 and 2010. In 2015, their primary venue changed to the Lee and Rose Warner Coliseum at the Minnesota State Fairgrounds, where they remain. Their secondary venues include Canterbury Park in Shakopee, Minnesota and the Minneapolis Convention Center. The league rebranded to North Star Roller Derby in 2017. TCRD and
